XTunnel is a program that allows you to encrypt TCP connections with XOR operator. Main purpose of this project is protecting online games from sniffing, analysing and hacking their weak protocol by using fast, simple encryption.

The TruongQuangDuocIDS (tqdids) is an IDS that works on multi-platform, from Solaris/SPARC to HP-UX/Alpha. This IDS has features like other IDSs (snort etc.) but it has a special feature inside the binary-pattern-matching algorithm that makes it faster.
